I just installed Alligate in front of my "decluded" mail server and it certainly cuts down alot of the traffic to the mail server. Previously the cpu on the declude mail server was 60-90% all day, now it rarely goes over 10%.
No more backscatter! No more dictionary attacks. Its pretty straightforward to configure and only took me about an hour or so. A small tip though in order to save all the pain of dns changes if you have many domains, to redirect all your smtp traffic to the Alligate server, you can configure your router to send all port 25 traffic to the Alligate server instead of the mail server. Declude is an excellent product, but add Alligate to it and you you are onto a winner.

From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Matt Sent: 28 May 2008 23:32 To: declude.junkmail@declude.com Subject: Re: [Declude.JunkMail] Mail Pre-Processor recommendations Scott, Alligate is a good gateway to use when you have something like Declude behind it. The only reason that I can think of that your Barracuda box is seeing that many messages would be because you might not be validating addresses. Like Andrew said, you can cut your connection traffic by 95% with ease, but a large number of those connections are to bad addresses (backscatter and 'dictionary' attacks). You must validate addresses at your gateway. You can run Alligate on a single core box with 1 GB of memory and a single hard drive. Just make sure to dedicate the box to Alligate in order to avoid issues when resources are that sparse.

I am hosting about 30 domains worth of email and filtering for an additional 10 domains. My current configuration is all mail is pre-filtered through a Barracuda 400 box, then forwarded to a Smartermail 4.x server running Declude with Sniffer, Zero Hour, invURIBL. The Smartermail/Declude box is a Dual Quad Core HP server with 2 Gig of RAM. I am currently receiving about 600k email messages a day on the Barracuda box, and it is seeing performance issues. Before I purchase a 2nd Barracuda box I though I would check to see if anyone has a better solution. Declude still catches 40-60% SPAM after the Barracuda box.
